Badger Meter 226 Specifications

Badger Series 200

The Badger Meter Series 200 ﬂ ow sensors feature a six bladed impeller design with a proprietary non-magnetic sensing mechanism. The forward swept impeller shape provides higher, more consistent torque and is less prone to be fouled by water borne debris. The forward curved shape coupled with the absence of magnetic drag provides improved operation and repeatability even at lower ﬂ ow rates. This is especially true where the impeller is exposed to metallic or rust particles found in steel or iron pipes. As the liquid ﬂ ow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the ﬂ ow rate. The signal can travel up to 2000 feet between the ﬂ ow sensor and the display unit without the need for ampliﬁ cation. All sensors except irrigation versions are supplied with 20 feet of 2-conductor 20 A WG shielded U.L. type PTLC 105°C cable.

MODEL 225BR AND 226BR/226SS SENSORS

The Model 225BR and 226BR/226SS sensors are used for ﬂ ow measuring applications in most metallic or non-metallic pipes where it would be difﬁ cult to shut down or drain the line for installation or service. The Model 225 features a gate valve for isolation. The Model 226 uses a ball valve. If the pipe is to be hot tapped, the ball valve is recommended. The sensor mounts in a 2” NPT pipe saddle or Threadolet® for installation in pipe sizes from 3” to over 40”. Positioning nuts on the three threaded retaining rods allow the sensor to be accurately positioned to a standard insertion depth of 1½” into the pipe. When this insertion depth is maintained, and there are at least 10 upstream and 5 downstream diameters of straight uninterrupted ﬂ ow, an accuracy of +/-1% of full scale can be obtained between ﬂ ow velocities of 0.5 to 30 feet/second. Each sensor is equipped with an isolation valve and pipe nipple to allow the sensor to be installed in a pressurized pipe. This is accomplished by ﬁ rst attaching a saddle or Threadolet® to the pipe and screwing the nipple and isolation valve into the saddle or Threadolet ﬁ tting. A hole is then drilled through the pipe using a commercial tapping machine. When completed, the tapping apparatus is removed, the isolation valve is closed, and the sensor is installed using a Model HTT Hot Tap Tool.
